Fix logging error for Guru Meditation Report
Fix logging error for Guru Meditation Report

Currently, invoking any of the commands under neutron/cmd will trigger a
"No handlers could be found" error for Guru Meditation Report. This is
interupting the notify.sh script that is called by dibbler-client during the
IPv6 Prefix Delegation workflow.

This patch adds a logging handler to __init__.py to prevent the error.

Without the error message being thrown, neutron-pd-notify is once again
able to complete successfully when called by dibbler-client.
